Title: Helical broach
Inventor: NISHIMURA AKIRA
IPC: B23D43/02
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To improve a cutting property by enhancing an effect of a tooth straight blade shape, to secure tooth shape precision and to reduce a lead error by making a helix angle of a screw type blade gullet the same or half of a helix angle of a tooth trace of a bearing. SOLUTION: The number of lines of a screw type blade gullet is made more than four, the number of blades in the same blade length is increased, a burden on each of cutting blades is reduced, and the burden is dispersed as the number of simultaneous cutting blades against an article to work on is increased. Additionally, a helix angle β of the screw type blade gullet is made more than 1/2 of a helix angle of a tooth trace of a bearing and less than the same of it, and tooth trace die wear is prevented. Hereby, as a lead of the blade gullet becomes longer as it approaches a tooth straight blade shape, an effect is provided by being superimposed with increase of the number of the lines of the blade gullet. A rake angle measured in the normal direction on a rake face functions as the helix angle on a finished blade.

Title: Honeycomb sandwich panel
Inventor: HAYASHI MASAHIKO
IPC: B64C1/00
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To strongly adhere a skin panel to a honeycomb core and to reduce a porosity in the panel very much by setting a woven fabric METSUKE of a reinforcing fiber woven fabric to a specific value range. SOLUTION: A skin panel is convenient in a production process preferably made of a prepreg or its laminate. In the honeycomb sandwich panel, reinforcing fiber woven fabric has a woven fabric METSUKE of 320 to 500 g/m2. If it is less than 320 g/m2, an exudation of a resin is deteriorated, and fillet formability is deteriorated, and surface smoothness of the panel might be lowered. If it exceeds 500 g/m2, resin impregnability of the resin when the prepreg is manufactured might be lowered. The reinforcing fabric having such a range of the METSUKE is preferable due to contribution to enhance a reducing effect of the manufacturing cost and the efficiency in the manufacturing steps.

Title: Stabilizer for semiconductor laser
Inventor: SHINOHARA SHIGENOBU
IPC: H04B10/54
Filed: 1985-03-05
Abstract: PURPOSE:To operate a normal semiconductor laser at a single mode having narrow spectral line width by modulating the intensity of return beams to the semiconductor laser from an external mirror to a weak value. CONSTITUTION:Beams projected from the end surface of a semiconductor laser 1 pass through a SELFOC lens 5, and one part thereof pass through a beam splitter 6a and an optical attenuator 8, is reflected by a liquid-crystal reflection type modulator 7, is projected to the end surface of the semiconductor laser 1 again, and is changed into return optical beams. A signal in which a high-frequency component in a phase error signal (e) is removed by a low-pass component filter 16 is amplified by a piezoelectric conversion element driving amplifier 17, and fed back negatively to a piezoelectric conversion element 18. Consequently, the liquid-crystal reflection type modulator 7 is moved in response to the phase error signal, and automatically adjusts the turnaround time gamma of return beams. When the gains and dynamic range of the amplifier 17 are sufficiently large within a range that they do not generate oscillations, the control system is operated stably, and the phase error signal (e) is kept to approximately zero at all times. That is, the phase difference of return beams is maintained at all times at a value in the vicinity of an in-phase point as an optimum value.

Abstract: PURPOSE:To easily execute editing operation after translation by simultaneously executing the automatic translation of a second language with the edition of a first language for the edition of the second language, to which the first language is translated. CONSTITUTION:When the character of an original sentence is inputted from an input part 4, the character code of the input character is stored in an original sentence storing part 5 and when the editing function key of the original sentence is inputted, an edition processing is executed based on the inputted editing function key. When a translation starting instruction is commanded from the input part 4, the original sentence stored in the storing part 5 is read and translated into English in a translating part 7. When the edition of the original sentence is finished, editing function is converted to editing function for English sentence based on an editing function translating dictionary part 9. Then, a translated sentence is edited based on the editing function of the English sentence. Thus, for the edition of the original sentence and translated sentence after the original sentence is translated, the editing function of the original sentence is translated for the translated sentence simultaneously with the edition of the original sentence. Then, the edition of the translated sentence can be automatically executed.
